Had rear quarter panels repainted last week. It's been a week and 2 days since I got it back. I know no wax or sealant for 30 days. I have no access to a hose over the weekend and my car is semi dirty. Mainly rain (dusty)spots. I would hand wash with gold class soap but not an option with no hose. In the meantime is Ecotouch waterless wash ok to use on the new paint? I just want to dust and get the spots off. I would use a microfiber. If that is no good what can I do? Just a wet microfiber maybe?
